Router booting U-Boot and shows 128 MB RAM. Smile
But linux kernel not starting without any error messages! Embarassed
Have you any ideas about starting linux kernel, what reason of this U-Boot or/and Firmware (DD-WRT, OPENWRT, Original firmware)?
This mod will be very intrested for many users who want to get small and fast home server.

Below U-boot logs with 128M and 64M:
